Braking
X
Keep the brake pedal depressed firmly until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. Active Brake Assist
General information i
Read the "Important safety notes" section
(Y page 66).
Active Brake Assist consists of a distance warn-
ing function with an autonomous braking func-
tion and braking assistance appropriate to the
situation.
Active Brake Assist can help you to minimise the risk of a collision with the vehicle travelling in
front or reduce the effects of such a collision.
If Active Brake Assist detects that there is a risk
of collision, you will be warned visually and
acoustically. If you do not react to the visual and audible collision warning, autonomous braking
can be initiated in critical situations. If you apply
the brake yourself in a critical situation, Adap-
tive Brake Assist supports you with braking
assistance appropriate to the situation.
Important safety notes Detection of hazardous situations can be par-
ticularly impaired by:
R
dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
R new vehicles or after servicing is carried out
on the Active Brake Assist system
Read the important safety notes in the "Run-
ning-in notes" section (Y page 132).
Following damage to the front end of the vehicle, have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at low speeds where no visible damage to the front of
the vehicle is apparent.
Activating/deactivating Active Brake Assist is active after every ignition
cycle.
You can activate or deactivate Active Brake
Assist (Y page 209) in the on-board computer.
When the system is deactivated, the distance
warning function and the autonomous braking
function are also deactivated.
If Active Brake Assist is deactivated, the æ
symbol appears in the assistance graphic dis-
play.
Distance warning function General information
The distance warning function can help you to
minimise the risk of collision with the vehicle in
front or reduce the effects of such a collision. If the distance warning function detects a risk of
collision with the vehicle in front, you will be
warned visually and audibly.
Important safety notes
i Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 66). G
WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations. Driving safety systems
67Safety
Z

In such cases, the distance warning function
may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation; do not rely on the distance warning
function alone.
Function The distance warning function issues a warning at speeds:
R of approximately 30 km/h or more if, over
several seconds, the distance to the vehicle
travelling in front is insufficient for the driving
speed. The ·distance warning lamp will
then light up on the instrument cluster.
R of approximately 7 km/h or more if you rap-
idly approach a vehicle in front. An intermit-
tent warning tone will then sound and the
· distance warning lamp will light up on
the instrument cluster.
X Brake immediately to increase the distance
from the vehicle in front.
or X Take evasive action provided it is safe to do
so.
Due to the nature of the system, certain com-
plex but non-critical driving conditions may also
cause the system to display a warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of approximately 70 km/h, the
distance warning function can also react to sta-
tionary obstacles, such as stopped or parked
vehicles.
Autonomous braking function If the driver does not react to the distance warn-
ing signal in a critical situation, Active Brake
Assist can assist the driver with the autonomous
braking function. The autonomous braking function:
R gives the driver more time to react to critical
driving situations
R can help the driver to avoid an accident or
R reduces the effects of an accident
Vehicles without Distance Pilot DISTRONIC:
the autonomous braking function is available in the following speed ranges:
R 7–105 km/h for moving objects
R 7 - 50 km/h for stationary objects
Vehicles with Distance Pilot DISTRONIC: the
autonomous braking function is available in the
following speed ranges:
R 7 - 200 km/h for moving objects
R 7 - 50 km/h for stationary objects
Due to the nature of the system, complex but
non-critical driving conditions may also cause
the autonomous braking function to engage.
If the autonomous braking function demands
particularly high braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously (Y page 53).
Braking assistance appropriate to the
situation General information
i Read the "Important safety notes" section
(Y page 66).
With the help of the radar sensor system, Adap- tive Brake Assist can detect obstacles that are in
the path of your vehicle for an extended period
of time.
If Adaptive Brake Assist detects a risk of colli-
sion with the vehicle in front, it calculates the
brake pressure necessary to avoid a collision. If
you apply the brakes forcefully, the braking
assistance adapts to the situation and automat-
ically increases the brake pressure to a degree
appropriate to the traffic situation.
Braking assistance appropriate to the situation
provides braking assistance in hazardous situa- tions at speeds above 7 km/h. It uses the radar
sensor system to assess the traffic situation.
Braking assistance appropriate to the situation
is capable of reacting to moving objects which
have already been recognised as such at least
once over the period of observation, up to vehi-
cle speeds of around 250 km/h. 68
Driving safety systemsSafety

Braking assistance appropriate to the situation
can also detect stationary objects, up to vehicle
speeds of around 70 km/h.
If braking assistance appropriate to the situa-
tion demands particularly high brake pressure,
preventative passenger protection measures
(PRE-SAFE ®
) are triggered simultaneously
(Y page 53).
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if: R you release the brake pedal
R a danger of collision with the vehicle in front
no longer exists
R no obstacle is detected in front of your vehicle
Braking assistance appropriate to the situation
is then deactivated.
Important safety notes i Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 66).G
WARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, Adaptive Brake Assist may not
intervene in all critical conditions. The risk of
an accident remains.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist might:
R intervene unnecessarily
R not intervene
The risk of an accident remains.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation. Due to the nature of the system, complex but
non-critical driving conditions may also cause
Active Brake Assist to intervene.
Even if Active Brake Assist is not available due to a malfunction in the radar sensor system, the
brake system is still available with full brake
boosting effect and BAS. Adaptive brake lights
The adaptive brake lights warn following traffic
in an emergency braking situation by: R flashing brake lamps
R the hazard warning lamps are activated
If you brake sharply from a speed of more than
50 km/h or if braking is assisted by BAS or BAS
PLUS, the brake lamps flash rapidly. In this way,
traffic travelling behind you is warned in an even more noticeable manner.
If you brake sharply from a speed of more than
70 km/h to a standstill, the hazard warning
lamps are activated automatically. If the brakes
are applied again, the brake lamps light up con-
tinuously. The hazard warning lamps switch off
automatically if you travel faster than 10 km/h. You can also switch off the hazard warning
lamps using the hazard warning button
(Y page 109). ESP
®
(Electronic Stability Program)
General notes i
Observe the "Important safety notes" sec-
tion (Y page 66).
ESP ®
monitors driving stability and traction, i.e.
power transmission between the tyres and the
road surface.
If ESP ®
detects that the vehicle is deviating from
the direction desired by the driver, one or more
wheels are braked to stabilise the vehicle. The
engine output is also modified to keep the vehi- cle on the desired course within physical limits.
ESP ®
assists the driver when pulling away on
wet or slippery roads. ESP ®
can also stabilise
the vehicle during braking. Driving safety systems
